The primitive shapes: Box, Sphere, Cylinder and Capsule are Shapes that offer good simulation performance, making them a good choice as collision shapes.

12.2. Trimesh Shape

A Trimesh Shape is a collision Shape represented by a collection of triangles. The triangles are read from an Unreal Engine Static Mesh, either via a Static Mesh Component or by referencing a Static Mesh asset.

On Linux it is currently required to enable General Settings > Advanced > Allow CPU Access on the Static Mesh asset for it to be usable with a Trimesh Shape in cooked builds.
